3 Claims. (Cl. 251-134) My present invention relates to a valve structure for an aerating bottle or the like in which liquid, such as cream or the like, is adapted to be aerated or similarly treated although the invention may be applied to other uses such as in connection with syphon bottles.

One object of my invention is to lprovide an aerator having a control valve structure of simple, durable and inexpensive construction.

Another object is to provide the control vlave structure in the form of an assembly which may be readily removed from the aerator and taken apart to permit ready access to all parts thereof exposed to liquid from the vase, for easy, quick and thorough cleaning thereof.

Another object is to provide a Valve assembly which when taken apart permits ready cleaning of the passageways leading to and from the valve, which passageways are short and direct for this purpose.

A further object is to provide a valve structure which may be readily operated by depressing a hand lever after the aerator has been filled with liquid and the liquid aerated, the -operating lever being readily removable during the disassembly of the valve parts with a minimum of eiort on the part of the user.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective View of an aerator or the like including a valve embodying my invention.

Figure 2 is an enlarged, vertical sectional view through the head -of the aerator showing the valve in closed position.

Figure 3 is a similar view showing the valve open.

Figure 4 is a horizontal sectional view on the line 4-4 of Figure 2, and

Figure 5 is an exploded sectional View with some of the valve parts in side elevation showing their separation for cleaning purposes.

On the accompanying drawings I have used the reference numeral I0 to indicate a vase adapted to receive liquid such as cream or an ice cream mix. Detachably mounted on the vase IIl is a vase head I2. The vase head I 2 is provided with screw threads I4 adapted to coact with threads of the vase II) in the usual manner so that the head may be attached and detached relative to the vase as desired.

In the vase head I2 I provide a vertical passageway I6 and a lateral passageway I8.v The passageway I6 terminates in a valve seat 2D and the passageway I8 leads to a decorating nozzle 22 screwed into the vase head I2.

The vase head has a pair of bores 24' and 26 aligned with the passageway I6 and of different sizes with the transition from one size to the other forming a shoulder 28. A combined gasket and .Valve plug element A is provided having a valve plug portion 30, a cylindrical diaphragm portion 32 and a gasket ring portion 34. The element A may be made of rubber or the like and the gasket ring 34 thereof seats on the shoulder 28. For seating the gasket ring on the shoulder, I provide a sleeve 36 having an inturned flange 38 at its lower end and an out-turned flange 40 at its upper end.

The flange 38 is adapted to contact the gasket ring 34 and a closure nut 42 is adapted to contact theflange 4U. The nut 42 is knob-like in character and is threaded onto the upper end of the valve head I2, indicated at 44, which end is threaded for this purpose. The upper end 44' has a notch 46 therein with which a displaced portion 48 of the sleeve 36 coacts for preventing rotation of the sleeve relative to the head.

A valve stem S is provided having a head 50 removably imbedded in the valve plug portion 30 of the element A, and an enlargement 52 between its lower and upper ends. A spring 54 is mounted between the enlargement 52 and the closure nut 42 for normally seating the valve plug 36 on the I valve seat 20.

The sleeve 36 is slotted at one side, as indicated at 56, and the head I 2 has a slot 58 aligned therewith. The head also has a pivotal projection 60, and a handle H is provided with a depression 62 for pivotal coaction therewith. The handle H has an opening 64 therein through which the stem S loosely extends and on opposite sides has a pair of projections 66 adapted to contact the lower edge of the enlargement 52.

Practical operation.

In the operation of my valve structure the vase I0 having been filled with cream or the like and the cream aerated by the introduction of gas under pressure, the apparatus can be used for dispensing the aerated cream by tipping it to an inverted position with the nozzle 22 pointing approximately downward and the valve may be opened from the position of Figure 2 to the position of Figure 3 by depressing the handle H. The

When it is desirable to clean the Valve structure this may be readily done by unscrewing the knob 42 so that all the parts shown in Figure 5 can be withdrawn from the head l2. The handle H is disconnectedI from the stem S after the head 50 of the stem hasbeen pulled outof the element A. Each of the parts may then be individually Washed and the passageways I6 and I8 cleanedout with a brush or the like as may also the bore portions 24 and 26 of the head- |22 The; device may thereby readily be kept in a sanitary'condi'- tion and after cleaning the valvefmay bei reassembled with a minimum oi effort,l on thel partv of the operator.

Some changes may be made. in. the construction and arrangement of the parts of my device Without departing from the real spirit and purpose of my invention, and it is my intention to cover by mycla'ims any modied formsxof structureA oruse of mechanical equivalents which may be reason--y ably included within their. scope without sacrificing any of the' advantages thereof.

I claim as my invention.
